When Goethe had to accompany his Duke Carl August, commander of a Prussian regiment, on the campaign against revolutionary France in 1792, he again met his "Cameraman" Johann Conrad Wagner, who had to administer the field cash of the ducal company of almost 40 men. Wagner has left extensive records that reflect the war in the years 1792/93 in its cruel reality. Goethe considered them valuable enough to use them decades later as a source of historical rank for his own performance, "Campaign in France 1792". In a strictly following, carefully commented and richly illustrated edition, Wagner's diary-like notes are made fully accessible for the first time.
